Luckily I purchased 2 of them so I'm presently using the other one that I didn't burn out.

The only thing it says on the box is "Mini IR High Speed Dome".

The small power distribution circuit board on top of the dome under the mounting arm with the 3A/250V fuse didn't protect the V1.3 circuit board from failing but it did protect the camera because I swapped the good circuit board from the other camera to this one and the dome booted up normally.

Does anyone know what chip is at location "D2"?

That chip fried but I retrieved the markings about the burnt chip from the good dome and I see: "1605 BV"

I've searched and searched Mouser, Digikey, Allied Electronics and can't seem to find a match for this chip.

Of course, any help from you guys on this little problem of mine would be awessome! " title="Applause" />
